Not a verdict per se, but this has potential, but is not there yet.
Pros: Decent reporting of the Download rates including intermediate values
Decent reporting for the idle latency (I like the box whisker plots,
ans the details revealed on mouse-over, as well as the individual samples)
Cons: Upload seems missing
Latency is only measured for a pre-download idle phase, that is
important, but for bufferbloat testing we really need to see the
latency-under-load numbers (separately for down- and upload).
Test duration not configurable. A number of ISP techniques, like
power-boost can give higher throughput for a limited amount of time, which
often accidentally coincides with typical durations of speedtests*, so being
able to confirm bufferbloat remedies at longer test run times is really helpful
(nothing crazy, but if a test can run 30-60 seconds instead of just 10-20
seconds that already helps a lot).
Best Regards
Sebastian
*) I believe this to be accidental, as the duration for "fair" power-boosting
are naturally in the same few dozends of seconds range as typical speedtests
take, nothing nefarious here.
